According to the link ZNP posted, Lucas has nothing to do with this 'canon', and considers it a parallel universe... like with Star Trek's stories. So to Lucas, if it didn't happen in the movies, it didn't happen.
You gonna trust a link or a guy with a Luke vs Vader tattoo on his chest?
Trust me, the books are canon.
TL:DR Here is an excerpt from the wiki about the levels of canon:
In 2000, Lucas Licensing appointed Leland Chee to create a continuity tracking database referred to as the "Holocron
". As with every other aspect having to do with the overall story of Star Wars
, the Holocron follows the canon policy that has been in effect for years. The Holocron is divided into five levels (in order of precedence): G-canon
, and N-canon
is absolute canon; the movies (their most recent release), the scripts, the novelizations of the movies, the radio plays, and any statements by George Lucas himself. G-canon overrides the lower levels of canon when there is a contradiction. Within G-canon, many fans follow an unofficial progression of canonicity where the movies are the highest canon, followed by the scripts, the novelizations, and then the radio plays.
refers to the canon level comprising only the two television shows: Star Wars: The Clone Wars
and the Star Wars live-action TV series
. Its precedence over C-Level canon was confirmed by Chee.
is primarily composed of elements from the Expanded Universe
including books, comics, and games bearing the label of Star Wars
. Games and RPG sourcebooks are a special case; the stories and general background information are themselves fully C-canon, but the other elements such as character/item statistics and gameplay are, with few exceptions, N-canon.
is secondary canon; the story itself is considered non-continuity, but the non-contradicting elements are still a canon part of the Star Wars
universe. This includes things like the online roleplaying game Star Wars: Galaxies
and certain elements of a few N-canon stories.
. "What-if" stories (such as stories published under the Star Wars: Infinities
label), crossover appearances
(such as the Star Wars
character appearances in Soulcalibur IV
), game statistics, and anything else directly contradicted by higher canon ends up here. N-canon is the only
level that is not considered official canon by Lucasfilm. A significant amount of material that was previously C-canon was rendered N-canon by the release of Episodes I–III.
Basically it is canon until the head honcho ruins it by rewriting it.
